Siemens Building Technology 186-0091 Pneumatic Duct Hygrostat 25-65% RH R/A Humidity Transmitter

The Siemens 186-0091 Pneumatic Duct Hygrostat is thus a specialized device that is used in HVAC systems for humidity control. This pneumatic hygrostat is just the right tool for maintaining the relative humidity in ducts, which is so essentialfor maintaining a comfortable climate and protecting equipment from corrosion. The 186-0091 Pneumatic Duct Hygrostat works through the process of determining the level of RH inside the duct systems, and then the output of the corresponding pneumatic control signals. It has a humidity control range of 25% to 65% Relative Humidity thus making it suitable for use in several applications where the RH is sensitive.
